The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Redundant and Flexible Electron Transfer Pathways Underlie MsrPQ‐Mediated Repair of Oxidized Periplasmic Proteins

Molecular Microbiology, EarlyView.
This study investigates in vivo the role of the flavin reductase Fre as an electron supplier to the periplasmic methionine sulfoxide reductase system MsrPQ. ABSTRACT The MsrPQ system is essential for the repair of oxidized methionine residues in periplasmic proteins, ensuring bacterial resistance to oxidative stress and envelope integrity.

Cytokinin downregulates Photosystem II photochemistry during prolonged darkness in a phytochrome B‐dependent manner

New Phytologist, EarlyView.
Cytokinin–phyB signaling modulates PSII photochemistry during prolonged darkness. Summary Cytokinins (CKs) delay dark‐induced senescence, but how they tune photosynthetic function in darkness remains unclear. We investigated the effects of classical aromatic CK benzylaminopurine and CK‐derived compound 1‐(2‐methoxyethyl)‐3‐(1,2,3‐thiadiazol‐5‐yl)urea ...

Plant Peptides on the Rise: From Historical Insight to Future Applications

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant peptides constitute a rapidly expanding class of signalling molecules essential to plant physiology, mediating key processes such as development, stress adaptation, and immune responses. This review traces the history of plant peptide research, from the seminal discovery of systemin to the recent identification of non‐canonical peptides (

PbrIDD2‐PbrAPX14 Module Functions in the Ethylene‐Mediated Ripening and Senescence Process of Pear Fruit

Plant Biotechnology Journal, EarlyView.
ABSTRACT Endogenous H2O2 participated in the ethylene‐dependent ripening and senescence process of horticultural fruit as a secondary messenger; however, the molecular mechanism beneath such a phenomenon has not been fully clarified until recently. By a conjoint analysis of metabolite, enzyme activities, gene expression profiles in AsA‐GSH cycle of ...

Persistent Erythrocytosis in a Dog With a Spinal Sclerosing Paraganglioma

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 7‐year‐old, male, castrated, mixed‐breed dog presented with right pelvic limb lameness and pain on posturing to defecate that began 1.5 years prior to presentation. Radiographs taken 8 months prior to presentation showed a small lytic lesion of the L6 vertebral body, and CBCs showed a persistently increased hematocrit (HCT) for at least 2 ...
